A simple:
eregi_replace("[^0-9]", "", $myvar);
should do it. it says.. replace everything that is not a number ( character class
"[^0-9]" which means Character class "[" NOT "^" of Decimal "0-9" end character class
"]" ) with a NULL string, thereby ripping out all non-numeric components and leaving
you with a totally numeric string. ( in theory ).
I haven't tested the code so you may have to play with it, but it's pretty simple.
